CT scans are relatively insensitive to the presence of cerebral lesions, so other neurological imaging such as EEG . In addition, motor visual function should be assessed through examination of pupillary reactions, ocular motility, optokinetic nystagmus, slit-lamp examination, visual field examination, visual acuity, stereo vision, bimicroscopic examination, and funduscopic examination.
